Specification of Letters Patent. Patented J 111) 27, 1915.

Application filed April 1 1915. Serial No. 21,327.

To all whom it may concern:

Be it known that we, SAMUEL T. EAS'I'ER and ERNEST E. COOK, Citizens ofthe'United States, residing at Aberdeen, in the county of Chehalis andStateof Washington, have invented certain new and useful Improve mentsin Leaf-Spring Lubricators, of which the following is a specification,reference r 1 are provided on either one or both sides being had to theaccompanying drawings.

This invention comprehends certain new and useful improvements in.meansor devices for use in lubricating leaf springs of automobiles or othervehicles, and the invention has for its primary object a simple, durableand efficient construction of device of this character whereby thelubricant may. be readily applied to the leaves and diffused.

A further object of the invention is to provide an improved leaf springlubricator which is so constructed and arranged that itwill not onlyserve its primary function as a lubricating device, but which 'will alsoserve the additional function of holding the tions of the parts that wetion, reference is to be had'to' the following:

leaves in proper alinement with each other, whereby all clips or similardevices may be done away with. And the invention also aims to generallyimproveand simplify de vices of this character so as to render them moreuseful, convenient and commercially desirable. 1 I

With these and other objects in view, as will more-fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinashall hereinafter describe and claim. 1 l

For a full understanding of the invendescription and. accompanyingdrawing, in which, c

Figure 1 is a side elevation of a leaf spring provided-with theimprovements of our invention. Fig. 2 is an inverted perspective view ofa portion of one of the leaves. Fig. 3 is a fragmentary perspective viewof one of the leaves-looking atthe upper face thereof. Fig. 4 is afragmentary transverse section of two of the leaves, and Fig. 5 is atransverse sectional view of a modified form of the device hereinafterspe; cifically referred to.

Corresponding and like partsare referred to in the following descri tionand designated in all of the views o the accompanymg draw ng by likereference characters.v

Referrmg to the drawing, the numera 1 designates the superposed leavesembodying an automobile or similar spring, and2 desigwith upwardlyprojecting tubular portions4 7 designed to receive the discharge ends.of-

the oil cans or the like, and comnrunicating at their lower ends withducts 5 1n the oil receiving devices, said ducts opening into the lowerfaces of the leaves and'there communicating with transversely extendinggrooves 7 formed in said faces.

From as much of the description as has preceded in connection with thecorrelated views of the accompanying drawing, it will be clearlyunderstood that when the oil is applied to the oil receiving devices 3,'it will flow down through the ducts 5 and across the grooves 7 andthence "be diffused between the adjoining faces of the leaves, wherebythe leaves. will be effectively lubricated and all squeaking and thelike obviated. In the preferred arrangement of the pa-rts,.the oilreceiving devices 3 are arranged in pairs, one foreach leaf with theexception of the lowermost one, the two oil receiving devices of eachspring being 10 cated respectively on opposite sides of the bolt orfastening device 9., and preferably all of the oil receiving devices arelocatedon the corresponding side edges of the leaves, namely, the outerside edge'whereby they will be easily accessible and the oper-' ation ofoiling the leaves thereby facilitated. But it is to be understoodthatthe invention is notlimited in this regard and that various changesmay be made in the construction, arrangement and proportions of theparts without departing from the scope of the invention as definedin theappended claims..- For example, if desired, the'upperrnost leaf alonemay be provided with oilreceiving devices, as clearly illustratedin'Fig. ,5, and.

the entire spring will thereby be lubricated. Various other changes willsuggest themselves to the designer, and still be within the scope of theinvention.

,devices 3 f each leaf extend above the adjoining 'side edge of the nextsuperjacent leaf, the oil receiving devices will subserve the additionalfuniition of holding the leaves in alinement and all clips or similarfastening devices can be done away with. Preferably, the main lug-likebody portions of the oil receiving devices directly serve this purpose,as their upper faces extend above the plane of the leaf to which theyare at tached or of which they form a part, so as to produce shoulders 9against which the side edge of the leaf above will bear. Preferably thelowermost pair of oil receiving devices 3 extends slightly below theadjoining side edge of the lowermost leaf so as to engage against theside edge of the leaf and prevent disalinement of this lowermost leafwith relation to the superjacent leaves.

It is to be understood that wherever the word oil is used in thespecification and claims, it-is intended-to be comprehensive enough tocover not only freely flowing oil, but all other substances oringredients that can be used as a lubricant.

What is claimed, is: L

1. A spring embodying a plurality of superposed leaves, and oilreceiving devices carried by said leaves, the oil receiving devices ofthe respective leaves engaging the oil receiving devices carried by therespective leaves on opposite sides of said bolt, said oil receivingdevices projecting laterally from the leaves and formed with ductsopening into the lower faces of the leaves, the oil receiving devicesbeing provided with shoulders abutting against the side edge of the nextadjacent leaf.

l. A spring embodying a plurality of superposed leaves and oil receivingdevices carried by said leaves on the side edges thereof, the oilreceiving devices on the leaf next to the lowermost leaf projectingbelow and in contact with the side edge of the leaf next below all ofsaid oil receiving devices of the respective leaves projecting above andin contact with the side edges of the leaf next above.

In testimony. whereof we hereunto affix nesses.
